How do you prevent tissue carryover during embedding?

Tissue carryover during embedding happens when tiny pieces of tissue cling to the instruments and get transferred to the next specimen. During embedding, forceps are used to place tissue into the molten paraffin. If any tissue sticks to the forceps, it can slip into the next mold and contaminate the next block. Wiping the forceps between specimens physically removes any residual tissue, stopping that transfer path and preventing cross-contamination. Other steps have value in other parts of processing, but they don’taddress the main way carryover occurs in embedding as directly. Clean blades matters during dissection and sectioning, changing embedding molds between samples helps avoid mixing by mold, and using separate paraffin blocks for each specimen reduces confusion and tracking errors, but wiping the forceps between specimens directly eliminates residual tissue on the instrument before it contacts the next sample.
